  Purpose

The objectives of the 2-year study are two-fold:

  1. To determine the 5-7 year patency rate (rate of open bypass grafts) of the LITA graft of patients who have already had robotically-assisted CABG surgery using CTA and MPS-MIBI
  2. To determine patient quality of life at 5-7 years after robotically-assisted CABG surgery

Condition Intervention
Coronary Artery Disease Procedure: MIBI and CTA

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Long Term Follow-up of Robotic Assisted Surgical Revascularization With CT Angiography

  Eligibility

Ages Eligible for Study:   30 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
All 150 living robotically-assisted CABG surgery patients will be contacted and their participation in the study requested. Patients will receive an initial request by mail, with an informative letter signed by the principal investigator outlining the purpose of the study, what participation in the study involves, and the specific aims of the cardiac team at the conclusion of the study. A follow-up phone call will be done within 3-weeks of mailing the letter to go over the content and answer any questions that patients may have.
Criteria

Inclusion Criteria:

  1. Have had previous robotically-assisted CABG surgery with a LITA to LAD anastomosis with either AESOP or Zeus performed between September 1999 and December 2001 at the London Health Sciences Centre
  2. Willing to give informed consent to participate in the study

Exclusion Criteria:

  1. Expired
  2. Unable or unwilling to give informed consent
  3. History of allergic reaction to contrast material used in CTA or severe adverse reactions to medications used in MPS-MIBI procedures
